It is anticipated that the use of tissue oxygen monitoring to measure brain tissue oxygen
and deltoid muscle oxygen will provide more precise information about focal brain ischemia
and systemic hypoperfusion than current techniques and measures such as blood pressure,
heart rate and intracranial pressure. Understanding the relationship between tissue oxygen
tension collected from the brain and deltoid muscle in critically injured patients could
lead to a broader understanding of the important metabolic and cellular events that occur
following severe injury and the changes induced by therapeutic interventions. Furthermore,
the use of interventions designed to improve tissue hypoxia, as measured by low brain or
muscle tissue oxygen, may improve mortality or neurological recovery after systemic trauma
or head trauma compared to current approaches that do not involve tissue metabolic
monitoring.
This is a prospective, observational, cohort study designed to investigate metabolic changes
in the brain and deltoid muscle of injured patients. Study objectives are as follows:
- To establish critical, abnormal levels of tissue oxygen in the brain (PbrO2) and muscle
(PmO2) of injured patients.
- To correlate PbrO2 with other currently available diagnostic measures used in
head-injured patients, including ICP, mean arterial blood pressure (MAP), CPP, SjO2, CT
findings, neurological examinations, and clinical outcomes from traumatic brain injury.
- To correlate PmO2 with base deficit measurements, standard physiologic variables, near
infra-red oxygen levels, infectious complications, and outcomes in critically injured
patients.
Investigators will enroll patients with multisystem trauma including brain injury. In
addition to the results obtained from oxygen monitoring, other data collected prospectively
will include:
1. Baseline Characteristics- mechanism of injury, arrival blood pressure and GCS, results
of imaging procedures, age, gender, blood gas analysis, injuries and injury severity,
and all operative procedures,
2. ICU Care - MAP, ICP, CPP, base deficit, oxygen saturation, CVP, cardiac output, GCS
scores, short-term outcome data, infectious complications and organ dysfunction.
All physiological data will be downloaded automatically and continuously from the bedside
monitor, ventilator, and oxygen monitors via a study-dedicated computer and customized
software (Aristein Bioinformatics, Palo Alto, CA).
